PCT No. PCT/EP96/03258 Sec. 371 Date Mar. 9, 1998 Sec. 102(e) Date Mar. 9, 1998 PCT Filed Jul. 24, 1996 PCT Pub. No. WO97/04706 PCT Pub. Date Feb. 13, 1997The invention concerns a device for determining data on auditory capacity, the device having preferably non-contact means for measuring vibrations of the middle-ear ossicles (22, 23, 24) and/or the tympanic membrane (21) by means of electromagnetic waves. The electromagnetic waves used for the measurement are input by means of a microscope (3), in particular an optical microscope (3). This microscope can be modular in design, and a module (5) can be provided for the input of a laser beam (9). The invention also concerns a method of determining data on auditory capacity, the method calling for the vibration of the middle ear and/or the eardrum to be measured by means of electromagnetic waves and, from the measurement signals thus obtained, the contributions to the total signal by the middle ear and/or the eardrum determined in at least one processing step.
